Enzymatic 11 [beta] HSD1 amplification of glucocorticoid concentrations in adipose tissue has been associated with obesity, diabetes, hypertension, dyslipidemia, and cardiovascular disease in humans and mice. Unfortunately, very little is known about 11 [beta] HSD1 in other species. Therefore, three species were studied to determine if 11 [beta] HSD1 activity existed in adipose tissue in a species dependent manner and if so, did the amount of enzymatic activity differ with respect to specific adipose depots within that species. Feline (carnivore): fat samples were collected from 6 cats, each sampled from 5 different adipose depots. immunohistochemically, 11 [beta] HSD1 was found in each of the adipose depots. Level of 11 [beta] HSD1 activity differed with depot and cat tested (P [less than] 0.05). Morphometric analyses revealed that adipocyte diameters differed (P [less than] .05) with adipose depot and cat, however, adipocyte volume did not correlate with level of 11 [beta] HSD1 activity. Equine (herbivore): fat samples were collected from the abdominal and subcutaneous adipose depots of 23 horses. immunohistochemically, 11 [beta] HSD1 was present in equine adipose, but level of activity did not differ with depot, nor body condition score of the horse. Porcine (omnivore): fat samples were collected from abdominal and subcutaneous adipose depots from 8 Ossabaw pigs. Immunohistochemical analysis revealed the presence of 11 [beta] HSD1 in porcine, but the level of activity did not differ between tissue depots.

Salov, Amanda
Human beings are ephemeral; our relationships are ever changing and our environments are transitory, yet we continually deny this basic principle. This transitory nature is an absurd beauty that encompasses the human condition. We should not view passing and change as a flaw, but as a quality of life that is consequently valuable. We often dismiss these incomprehensible moments far too quickly. Yet, when we embrace this space of the unknown it has the potential to alter notions of our relationships. I present the essence of temporal beauty in my sculptural work. I am showing - through the indirect and deviously flexible nature of the forms - that process and change are constant and we do affect and alter our relationships. I want the work to find the space between things that divides the soft and hard qualities, which we all possess. When this space of vulnerability is exposed, we grow.

One job of social scientists is to parse out partial knowledge from every relevant social location in order to present a structural interpretation of social phenomena. A textual and content analysis was performed on both academic texts and internet blogs that discusses white privilege from a lower class white social location to gain an emic and etic perspective and to discover if a disconnect between knowledge claims exist between the two perspectives. The analysis of emic texts revealed four themes: (1) White privilege contributed a lack of understanding that whites could legitimately be poor (2) Group boundaries were constructed between racial minorities and non-poor whites (3) White privilege does not exist for the emic and (4) Some understanding of the intersection with gender and social class was evident. A content and textual analyses of academic texts lead to the discovery of three patterns (1) Whites from various classes were compared only to lower class racial minorities (2) Lower class whites emically adopted a vicarious status with the help of their racial privilege to improve their material situation and (3) the emic complained about class oppression is it was judged that the gap between them and racial minorities was too small. The analysis revealed that the emic lower class white perspective included a partial understanding of white privilege because class and gender oppression must be taken into account for a more accurate understanding. Implications of the study suggest that intersectionality must be incorporated in the etic analysis, and when it is included more effort to parse out partial knowledge must be made.

Rodvelt, Kelli Renee, 1981-
Blockade of ionotropic glutamate receptors can induce changes in central dopamine and glutamate circuits, which model the symptoms of schizophrenia. Nicotine evokes dopamine release through activation of nicotinic acetylcholine receptors, and human research indicates that nicotine improves negative and cognitive symptoms of schizophrenia. The objective was to determine the effect of the glutamate receptor antagonist, ketamine, on the function of nicotinic receptors that mediate dopamine release. Ketamine did not have intrinsic activity to evoke dopamine release from rat striatal or prefrontal cortical slices. Acute NMDA receptor blockade augmented the effect of nicotine to evoke dopamine release. To model progression of schizophrenia, rats received injections of either a high or low dose of ketamine or vehicle for 30 days and then nicotine-evoked dopamine release was measured. Subchronic NMDA receptor blockade altered the effect of nicotine to evoke dopamine release. Overall, these data indicate that nicotinic receptor function is altered in this model of schizophrenia, and support a role for nicotinic receptors in schizophrenia treatment.
